Best answer
` C_4 H_4 O_4+ 3O_2 " "to 4CO_2 + 2H_2 O `
` " " 4xx 44 =176 " "2xx18=36`
(` C_4 H_4 O_4 ` का सूत्रभार ` = 4xx12 + 4 xx1+ 16= 16`)
` therefore " " 116 g ` योगीक से 176 g `CO_2 ` मिलता है|
` therefore " " 0.25 " " (176xx0.25)/( 116 ) g CO_2 ` मिलता है|
` " "= 0.3793g CO_ 2 .`
फिर ` therefore ` 116 g यौगिक से 36 g जल मिलता है,
` therefore 0.25" " (36xx0.25)/( 116 )g ` जल मिलता है
` " "=0.07758g ` जल|
